TL;DR: FotoFile is an experimental system for multimedia organization and retrieval, based upon the design goal of making multimedia content accessible to non-expert users that blends human and automatic annotation methods.
Abstract: FotoFile is an experimental system for multimedia organization and retrieval, based upon the design goal of making multimedia content accessible to non-expert users. Search and retrieval are done in terms that are natural to the task. The system blends human and automatic annotation methods. It extends textual search, browsing, and retrieval technologies to support multimedia data types.

TL;DR: This paper explores the use of hypertext to enhance the process of component selection through a prototype system called Kiosk, and discusses the selection process, why hypertext is well suited for supporting selection, and important characteristics ofhypertext systems intended to support reuse.
Abstract: software reuse; software libraries; component selection; hypertext; Kiosk. Recently, there has been increasing interest in software reuse as a way to improve software quality and productivity. One of the major problems with reusing libraries of software components is helping users effectively select (find and understand) components of interest. This paper explores the use of hypertext to enhance the process of component selection through a prototype system called Kiosk. Included are discussions of the selection process, why hypertext is well suited for supporting selection, and important characteristics of hypertext systems intended to support reuse. Also discussed are how reusable libraries can be structured using hypertext, how these structured libraries can be mechanically built, and how their use enhances the component selection process.

TL;DR: The incentives for annotation in Flickr, a popular web-based photo-sharing system, and ZoneTag, a cameraphone photo capture and annotation tool that uploads images to Flickr are investigated to offer a taxonomy of motivations for annotation along two dimensions (sociality and function).
Abstract: Why do people tag? Users have mostly avoided annotating media such as photos -- both in desktop and mobile environments -- despite the many potential uses for annotations, including recall and retrieval. We investigate the incentives for annotation in Flickr, a popular web-based photo-sharing system, and ZoneTag, a cameraphone photo capture and annotation tool that uploads images to Flickr. In Flickr, annotation (as textual tags) serves both personal and social purposes, increasing incentives for tagging and resulting in a relatively high number of annotations. ZoneTag, in turn, makes it easier to tag cameraphone photos that are uploaded to Flickr by allowing annotation and suggesting relevant tags immediately after capture. A qualitative study of ZoneTag/Flickr users exposed various tagging patterns and emerging motivations for photo annotation. We offer a taxonomy of motivations for annotation in this system along two dimensions (sociality and function), and explore the various factors that people consider when tagging their photos. Our findings suggest implications for the design of digital photo organization and sharing applications, as well as other applications that incorporate user-based annotation.

TL;DR: Based on a workshop discussion of multiple views, and based on the authors' own design and implementation experience with these systems, eight guidelines for the design of multiple view systems are presented.
Abstract: A multiple view system uses two or more distinct views to support the investigation of a single conceptual entity. Many such systems exist, ranging from computer-aided design (CAD) systems for chip design that display both the logical structure and the actual geometry of the integrated circuit to overview-plus-detail systems that show both an overview for context and a zoomed-in-view for detail. Designers of these systems must make a variety of design decisions, ranging from determining layout to constructing sophisticated coordination mechanisms. Surprisingly, little work has been done to characterize these systems or to express guidelines for their design. Based on a workshop discussion of multiple views, and based on our own design and implementation experience with these systems, we present eight guidelines for the design of multiple view systems.

TL;DR: Applied to face detection, the FloatBoost learning method, together with a proposed detector pyramid architecture, leads to the first real-time multiview face detection system reported.
Abstract: A novel learning procedure, called FloatBoost, is proposed for learning a boosted classifier for achieving the minimum error rate. FloatBoost learning uses a backtrack mechanism after each iteration of AdaBoost learning to minimize the error rate directly, rather than minimizing an exponential function of the margin as in the traditional AdaBoost algorithms. A second contribution of the paper is a novel statistical model for learning best weak classifiers using a stagewise approximation of the posterior probability. These novel techniques lead to a classifier which requires fewer weak classifiers than AdaBoost yet achieves lower error rates in both training and testing, as demonstrated by extensive experiments. Applied to face detection, the FloatBoost learning method, together with a proposed detector pyramid architecture, leads to the first real-time multiview face detection system reported.

TL;DR: The file system shell as discussed by the authors provides virtual folders which expose regular files and folders to users in different views based on their metadata instead of the actual physical underlying file system structure on the disk.
Abstract: A file system shell is provided. One aspect of the shell provides virtual folders which expose regular files and folders to users in different views based on their metadata instead of the actual physical underlying file system structure on the disk. Users are able to work with the virtual folders through direct manipulation (e.g., clicking and dragging, copying, pasting, etc.). Filters are provided for narrowing down sets of items. Quick links are provided which can be clicked on to generate useful views of the sets of items. Libraries are provided which consist of large groups of usable types of items that can be associated together, along with functions and tools related to the items. A virtual address bar is provided which comprises a plurality of segments, each segment corresponding to a filter for selecting content. A shell browser is provided with which users can readily identify an item based on the metadata associated with that item. An object previewer in a shell browser is provided which is configured to display a plurality of items representing multiple item types.
